+ *
+ *   Associations are nodes that match to something else through an ID:

+ *
+ *   The `label` of an association is the string value: character escapes and
+ *   references work, and casing is intact.

+ *   controversially, character escapes and references don’t work in this
+ *   matching: `&copy;` does not match `©`, and `\+` does not match `+`.
+ *
+ *   But casing is ignored (and whitespace) is trimmed and collapsed: ` A\nb`
+ *   matches `a b`.
+ *   So, we do prefer the label when figuring out how we’re going to serialize:
+ *   it has whitespace, casing, and we can ignore most useless character
